BRACKET Filed Jan. '7, 1935 ATTO R N EY Patented Feb. 25, 1936 UNITED STATES PATENT OFFICE Application January '1, 1935, serial No. 765` 3 Claims.I (Cl. 248-245) 'Ihis invention relates torbrackets and espe companying drawing and consists in certain novel features which will be hereinafter first fully described and then more' particularly defined in the appended claims.

In the drawing:

Figure 1 is a side elevation of a. scaffold bracket embodying the invention.

Figure 2 is a section on the line 2 2 of AFigure 1. Figure 3 is a section on the line 3-3 of Figure 4.

- Figure 4 is a view, partly in section and partly.

in elevation, showing the manner of adjusting the bracket.

Referring now to the drawing in more detail, the numeral I designates a tubular standard or pipe which may have its lower end secured in a flange 2 or otherwise provided with a footing. As many standards as needed may be set up along the line of work and they may be connected and braced by bars 3 clipped thereto as shown and asv will be understood. The bars 3 may be multiplied and arranged at intervals in the height of the standards and additional pipes or standards may be added as needed. To extend the standard, a

peg or alining rod, indicated at 4; is fitted snugly in the upper end of the pipe and may be secured byv a set screw 5, a portion of the rod projecting up beyond the end of the pipe. A second pipe 6 then has its lower end fitted over the projecting end portion of the rod so as to rest on the end of the pipe I, the rod holding the two pipes in alinement and any preferred means being utilized to brace the upper pipe.

Above the connecting bar 3, a sleeve 'I is fitted on the pipe I, said sleeve having a perforated lug or ear 8 on one side. To said lug or ear is pivoted the upper end of a bracing rod 9 which has its lower end fitted snugly but slidably in the upper end of a tube I0, said tube having its lower end anchored at or in the ground and a set screw II holding the parts in a set position in an obvious manner.

Mounted upon thepipe or standard I, at a proper point in the height thereof, is a. sleeve I2 having the lower end of its bore flared, as shown at I3, and having diametrically opposite circular lugs I4 at its upper end, flanges I5 being provided between the lugs, and the outside surface of the sleeve at the lugs being plane. A foot or claw is carried by the sleeve I2 and consists of a fork or yoke I6 and an upstandng'toe II at the outer end of the fork, the fork spanning the sleeve and being provided in its sides with circular openings to fit over the lugs I4 and establish pivotal connection between the sleeve and the fork. The 5 sides of the fork are rabbeted on their inner faces,

as shown at I8, and arcuate cheek pieces I9 are secured in the rabbets and depend therefrom, slots 20 being formed in the ends of the cheek pieces slightly eccentric to the pivot points I4. A 10 split bushing 2| is mounted on the pipe I between the cheekplates I9 and has its upper portion 22 tapered to :lit yin the ared bore of the sleeve I2,

as clearly shown in Figures 2 and 4. At diamet. rically opposite points of the lower end of the 15 bushing are lugs 23 which engage in the slots 20 and washers 24 are disposed over said lugs and slots and secured to the lugs by set screws 25 to frictionally bear upon the cheek plates.

If the claw or foot be swung upward, as shown 20 in Figure 4, the bushing will be slightly lowered, owing to the action of the slots 20 on the lugs 23, and will be permitted to expand slightly to release its grip on the pipe. 'Ihe device may be' then raised or lowered or turned about the pipe 25 to any desired position and, when that position has been reached, may be secured by merely Y swinging the claw down to the horizontal position shown in Figure 1. When the claw is thus swung downward, the bushing will be raised into engage- 30 ment with the sleeve, as shown in Figure 2, and a wedging action will occur to bind the bushing in the sleeve and around the pipe whereby the device will be securely held in the set position.

While the bushing will securely hold the device, 35 I prefer, as a matter of precaution for safety, to mount a set screw 26 in the upper end of the sleeve I2, a. lock nut 21 being fitted on the screw to prevent loosening thereof and a clamping plate 28V being fitted to the inner end of the screw to 40 bear against the pipe I.

It will be understood that foot boards are laid across the several feet or claws to constitute a platform for workmen and'. the toes I1 prevent the boards slipping over the ends of the feet.

Having described my invention, what I claim is' .1. `A bracket comprising a standard, a sleeve .mounted on the standard, a foot pivoted on the sleeve and extending laterally therefrom, and a split bushing carried by the foot below the sleeve and carried by pivotal movement of the foot into binding engagement with the sleeve and the standard.

2. A bracket comprising a standard, a sleeve 10 mounted thereon and having a flared bore ln its lower end, a foot pivoted on the sleeve, a. split bushing mounted on the standard and having a tapered upper end to t in the ared bore of the sleeve andprovided with lugs at its lower end, and cheek plates secured to and depending from the foot and having slots eccentric to the pivot of the foot and engaging over the lugs on the bushing.
